We don't. The BeforeScroll event should fire immediately before the dataset scrolls to
another record as a result of a change of record as observed by the end-user. (First,
Last, MoveBy, Next, Prior, Find, Locate, Search, Filter)

If it fires for any other reason then a separate parameter is required that provides the
reason for the scroll.

Currently it is indeed mostly useless and changing this particular event will most likely
affect no-one.
